Specification of letters Patent.

Patented May 22, 1917.

Application filed September 16, 1915. Serial No. 50,979.

Essex and State of New Jersey, have 1nvented a new and Improved Collapsble Tube for Paste, of which the following 1s a full, clear, and exactdescription.

This invention relates to collapslble tubes for holding paste material.

The invention has to deal more particularly with means whereby theexternal s1 1r face of the tube can be printed in a plurality of colorsexpeditiously, accurately and economically.

Heretofore in printing collapsible tubes in several colors great carewas necessary on the part of the operator to so place the tubes on theprinting mandrel as to 1nsure proper registration of the successlyeimpressions. Considerable tlme and Sklll is required to properly place atube on a mandrel, so that the cost of prmtlng has been unduly largebecause of the limited number of tubes that can be printed 1n a giventime according to the oldmethod,

The object of the present 1nvent1on 1s to insure a proper placing of atube on the mandrel so that successive colors w ll abso lutely register,this registerlng-insurrng means being so designed that the attendantdoes not have to be especially skilled or experienced, as the mereplacing of the tube longitudinally on the mandrel and turnmg the tubeback or forth will interlock the mandrel and tube, the interlockingmeans being so designed that the tube can be locked to the mandrel inonly one position, so that the successive impressions or colors mustregister. By this means the outp1 1t of the printing machine is manytlmes increased over the old method of operation.

For a more complete understanding of the invention, reference is to behad to the following description and claims taken 1n connection with theaccompanying dravvlng, wherein similar characters of reference indicatecorresponding parts in all the vlews, and in which- Figure 1 is a sideview of an empty collapsible tube with a portion broken away to show thelug on the internal surface of the H. NEIDLIN-- GER, a citizen of theUnited States, and a resident of East Orange, 1n the county of head thatengages with the mandrel to cause proper positioning of the tube;

Fig.2 is an enlarged transverse section on the line 22, Fig. l; v

Fig. 3 is an enlarged sectional view of the tube mounted on the mandreland receiving an impression from the printing element;

and

Fig. 4 is a fragmentary detail view of a modified form of the invention.

Referring to the drawing, A designates a collapsible tube for holdingpaste stock, the tube comprising a pliable body 1, which,

when empty, is open at the end 2 and has a comparatively stiff head 3provided with a discharge nozzle 4. On the head 3 and disposedinternally of the tube is a suitable means adapted to interlock with themandrel that supports the tube during the printing of matter onthecircumferential external surface ofthetube. Thismeansis preferably a lug5 which is so shaped as to enter a recess or socket 6 in the end of themandrel B of the printing machine. The. tube A is interlocked with orkeyed to the mandrel by slipping the tube longitudinallv on the latterand turning the tube in one direction or the other while maintaining aninward pressure on the tube so as to cause the lug 5 to enter the recess6, and when this is effected, the tube will be in the proper position toreceive an impression. This act is repeated every time the tube isplaced on the mandrel to receive another impression of color, and sincethe tube can have only one position on the mandrel it follows that allthe impressions are positively registered. The lug 5 may be of anydesired shape, and if desired the lug may be placed on the mandrel, asindicated at 5, Fig. 4, and the depression or recess 6 may be arrangedin the head of the tube.

In Fig. 3 the printing element C is shown in the act of printing animpression on the tube, which is rotated with the mandrel.

From the foregoing description taken in connection with the accompanyingdrawing, the advantages of the construction and method of'operation willbe readily understood by those skilled in the art to which the inventionappertains, and while I have described the principle of operation,together with the article Which I noW consider to be the best embodimentthereof, I desire to have it understood that the article shown is merelyillustrative and that such changes may be made When desired as fallWithin the scope of theappended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A collapsible paste-holding tube hav- 'ing on the inner surface ofits head means for interlocking with the mandrel of a printing machineto insure registering of successive impressions printed on the tube.

2. A collapsible tube for holding paste,

com-prising a body, a head on one end thereof, a discharge nozzle at thecenter of the ing machine to insure registering of impressionssuccessively applied to the external surf-aceof the body.

3. A collapsible tube for holding paste or the like, comprising atubular body, of round cross-section, a head at one end of the body, adischarge opening at the center of the head, and integral means on theinternal surface of the head for interlocking With a mandrel of aprinting machine for insuring registering of successive impressions.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
